How we approach bespoke & shaped rooflights in Bath
We handle bespoke & shaped rooflights across Somerset, including Bath. In short: triangular, angled, curved and multi-pane rooflights made to measure. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. In Bath, as anywhere, bespoke & shaped rooflights are the usual choice for angled ceilings, corners and architect-designed extensions.
Bath is the main town we list in Somerset; we also cover nearby Trowbridge and Kingswood.

Planning and building rules for Bath
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about bespoke & shaped rooflights in Bath
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
